VMware: Set vmPathName properly in fake driver
VMware: Set vmPathName properly in fake driver

When creating a VM, we pass in config.files.vmPathName as '[ds]'.
However, when this value is subsequently retrieved from a real vSphere
server, it is '[ds] uuid/uuid.vmx'.

This change defaults the value of vmPathName if it's a bare datastore
name to mirror the behaviour of a real vSphere server.
